In modern manufacturing environments, speed, efficiency, and communication are everything. One tool that continues to prove its value on the production floor is the Andon system—a visual management tool that helps streamline processes and minimize downtime. Among the many components of an Andon system, Red and Yellow Andon lights play a crucial role in keeping operations running smoothly.
What Is an Andon System?
An Andon system is a lean manufacturing tool used to provide real-time visual feedback about the status of a production line or process. It typically includes colored lights, display boards, and sometimes audible alerts to notify team members of any issues that arise. The goal is to make problems immediately visible so they can be addressed quickly.
Understanding Red and Yellow Andon Signals
Red Andon Light:
This is the most critical signal. A red light usually means a stop in production due to a significant issue—equipment failure, quality problem, or safety concern. It requires immediate attention from supervisors or maintenance staff.
Yellow Andon Light:
A yellow light serves as a warning. It often indicates a minor issue or a request for help from an operator. Yellow allows intervention before the problem escalates into a full production halt.
These color codes are easy to understand and help eliminate communication delays on the shop floor.
Why Are Red and Yellow Andon Systems Important?
Here are some reasons why implementing a visual alert system with red and yellow Andon signals is critical in modern manufacturing:
✅ Real-Time Communication: Alerts teams instantly when something goes wrong.
✅ Faster Response Time: Issues are resolved quicker, reducing downtime.
✅ Improved Productivity: Keeps the workflow steady by preventing problems from snowballing.
✅ Employee Empowerment: Operators feel confident reporting issues without delays.
✅ Supports Lean Principles: Encourages transparency, accountability, and continuous improvement.
